====== macOS ======

Platform-specific code for macOS. Everything in this module, including the headers, is wrapped in the following preprocessor macro

<code c>
#if defined(__APPLE__) || defined(__MACH__)
/* 
... code ...
*/
#endif /* defined(__APPLE__) || defined(__MACH__) */
</code>

===== Structs =====

==== ProcessData ====

ProcessData is a struct that tracks cpu and memory usage of a process. It needs to be regularly updated with calls to ''%%update_process()%%'' in order to provide accurate information

<code c>
typedef struct {
double total_user_time;
double total_kernel_time;
double last_total_consumed;
double percent_cpu;

uint64_t virtual_memory;
uint64_t resident_memory;

time_t timestamp;
time_t last_timestamp;
} ProcessData;
</code>

===== Functions =====

===== new_ProcessData =====

Returns a pointer to a ''%%ProcessData%%'' struct.

<code c>
ProcessData *new_ProcessData();
</code>

===== update_process =====

Updates a ''%%ProcessData%%'' struct. This should be called in a loop or at specific intervals to measure proper usage data. An example is below

<code c>
int update_process(pid_t pid, ProcessData *proc);

/* Example */
pid_t pid = getpid();
ProcessData *pd = new_ProcessData();
for (int i = 0; i < 10; i++) {
    update_process(pid, pd);
    printf("CPU: %.2f\n", pd->percent_cpu);
    sleep(1);
}
free(pd);
